MySQL: Calculate depth in a parent-child model?
As title says: How do I calculate a node's depth in a parent-child model? I'll need the depth to, among other things, create the indent in my list (coded with PHP). Thank you in advance. ...

Hey There! I use Xcode to code for a current iPhone Project. It's the first time i work with XCode. What i wonder is, whether i need to set somewhere how 'deep' i can be able to recursively look into the variables in the debugger. If i have the debugger open, i can see all the current variables and open them. I can see all the fields o...
Hi all, I am trying to develop a java algorithm for the enumeration of n-depth and m-width trees: Each node can have at maximum 7 children. Nodes are of different type: a first kind of node can have children but can not be a leaf. The second can have no child (so it must be a leaf). The root is at depth 0 and the width is the maximum ...
Hi there I found a tutorial on creating a stack of photos in flash using AS3 (http://designreviver.com/tutorials/create-an-interactive-stack-of-photos/). I have been trying to make a dynamic XML version of the photo stack and I have a problem (obviously :) I have a class called Polaroid, and im using a loop to add multiple instances o...
If T is a balanced BST with n elements, L its left subtree and R its right one, how can I prove that its depth is less than or equal to 2log(n) + 1? There is a proof by induction which I have but I don't get it. (I understand that stackoverflow is mainly programming oriented but I found some questions about binary search trees and dec...
From this site: http://www.catalinzima.com/?page%5Fid=14 I've always been confused about how the depth map is calculated. The vertex shader function calculates position as follows: VertexShaderOutput VertexShaderFunction(VertexShaderInput input) { VertexShaderOutput output; float4 worldPosition = mul(input.Position, World)...
I am having difficulty calculating the summation of depths [the sum of the individual depths for all children of the root] for a given BST. I have the total number of nodes for the tree, and I am trying to calculate the average depth for the tree, requiring I have this depth sum. Recursion and I don't get along very well.. I am finding ...
Hello, I am developing a game that intends to toss an object but instead of having it being tossed horizontally I would like to simulate it being thrown along the imaginary z axis that is simulate depth in my game. Something like the nintendo duck hunt game. Can someone point me in the right direction to implement this?. My first idea w...
I have a huge array from a json_decode result (assoc set to true) and have the following code to check if (one of the arrays within, a random serial) has the key 'set_true' $out = ""; foreach ($array as $sub) { //$out[] = $sub['set_true']; if (in_array($sub['set_true'], $sub) && $sub['set_true'] == '1' ) { $out[] = 'User: ' . $...
The background: I'm building a trie to represent a dictionary, using a minimal construction algorithm. The input list is 4.3M utf-8 strings, sorted lexicographically. The resulting graph is acyclic and has a maximum depth of 638 nodes. The first line of my script sets the recursion limit to 1100 via sys.setrecursionlimit(). The prob...
I see that others are reporting bugs relating to a spurious "Stack depth is unbalanced" error, so I don't know whether the error I'm getting is my programming error or a bug in FB4 b2. It it legal to instantiate a class that raises an event in an eventHandler? I'm getting such an error at the place located below. All of these classes ex...
For a balanced search tree, it is O(log(N)) for all cases. For unbalanced search trees, the worst case is O(N), e.g., insert 1, 2, 3, 4,.. and best case complexity is when it is balanced, e.g., insert 6, 4, 8, 3, 5 7. How do we define the average case complexity for unbalanced search tree? ...
I am currently writing the positions of my geometry to the RGB channels of gl_FragColor and I would like to write 1.0 to the alpha channel if the fragment is part of geometry, and 0.0 if its empty. Is there a simple way to tell if a fragment is geometry or not? Maybe through gl_FragCoord.z? thanks ...
I am working on a coloring book and have a movieclip (outlines) containing many movieclips that can be changed to whatever color the user has selected. However it seems like some of the movieclips can be clicked anywhere and work great, and others you need to click a certain spot for it to color in. I have an example here: http://jeffki...
Question for Flex guys. How can I use multiple item renderers in mx:Tree depending on item's depth/level in tree? For example. For the first level items I want to use label with button and for second level items combobox. Is this somehow possible? ...
Hi, is it somehow possible to get item's depth in ArrayCollection? ...
Hi all. May I know is it true that a java applet only supports 24 bits image? If a 48 bits image is loaded, it will be truncated to 24 bits? Thank you. ...
I need a datastructure of the same size as the normal depth buffer and I need to be able to read from and write to it in a shader. Is this possible, and what does this datastructure look like? ...
I'm trying to implement an old-school technique where a rendered background image AND preset depth information is used to occlude other objects in the scene. So for instance if you have a picture of a room with some wires hanging from the ceiling in the foreground, these are given a shallow depth value in the depthmap, and when rendered...
Are there any AS3 classes to help arrange objects into layers, like in the designer, such that the objects all have the same parent? Obviously, I can use container clips to simulate layers, but I specifically want this kind of functionality for objects that have the same parent. My understanding is that the design-time notion of layers...
